The app-detail page was the last corner of the SPA still using query
parameters for navigation state. Two related complaints surfaced it:
- `/app/adguard?tab=tasks` should mirror admin (`/admin/tools/peers`,
`/admin/config/network`) and be `/app/adguard/tasks`.
- The config sub-tab (general / advanced / features / network / …)
had no URL representation at all — `showTab` was a pure visual
swap with no history push, so refreshing a deep config sub-tab
sent the user back to the default first category.
New URL shape:
/app/<name> → config tab, default sub-tab
/app/<name>/<tab> → non-config main tab (tasks, backups, …)
/app/<name>/config/<category> → config tab + specific sub-tab
…?task=<id> → optional deep-link to a single task
Mirrors `adminPath` / `adminCategoryFromPath`. Two new helpers in
spa.js carry the convention:
window.appPath(name, tab, sub, taskId) → URL
window.appPartsFromPath(pathname) → { app, tab, sub }
Every URL constructor in the WebUI was replaced with `window.appPath`:
spa.js — handleAppDetail back-compat redirect
app-tabbed-manager.js — getTabFromURL + new getConfigSubFromURL
(path first, ?tab= fallback for legacy)
updateURL + updateApp use appPath
the inline task-deep-link constructor
apps-manager.js — showAppDetail + showAppDetailWithConfig
showTab now pushes /app/<n>/config/<sub>
renderAppDetail picks the sub-tab out of
the URL on first load
4 fallback task-URL constructors
tasks-manager.js — completion-notification URL
task-actions.js — start-notification URL
notifications.js — 2 task deep-link URLs
Back-compat: handleAppDetail detects legacy `?tab=` / `?config=` /
`?task=` queries and replaceState()s the URL to the canonical path
shape BEFORE anything else reads URL state — old bookmarks land on
the right page and end up with a clean URL.
Verified by running every appPath / appPartsFromPath case (including
the `logs` → `tasks` legacy alias) and confirming the round-trip is
identity. JS syntax checks clean on all six files. No remaining
hardcoded `/app/<x>?tab=` strings outside the back-compat comment.
